Jakasia needed to find the volume of a plastic container in L to see if the 170 L of
solution that she had would fit inside. She knew that one side was 2.5 ft, the
height of the box was 60 cm, and width of the box was 0.8 m. Use dimensional
analysis to determine if Jakasia's solution will fit in the container.
Answer:
The solution will fit into the container.
Explanation:
The following data were obtained from the question'
Volume of solution = 170 L
Length of container (L) = 2.5 ft
Height of container (H) = 60 cm
Width of container (W) = 0.8 m
Volume of container (V) =?
Next, we shall express the length, height and breadth I the same unit of measurement. In this case, we shall all in centimetres (cm).
For the length:
1 ft = 30.48 cm
Therefore,
2.5 ft = 2.5 ft × 30.48 cm / 1 ft
2.5 ft = 76.2 cm
Thus the length is 76.2 cm
For the width:
1 m = 100 cm
Therefore,
0.8 m = 0.8 m × 100 cm / 1 m
0.8 m = 80 cm
Thus, the width of the container is 80 cm.
Next, we shall determine the volume of the container as follow:
ength of container (L) = 76. 2 cm
Height of container (H) = 60 cm
Width of container (W) = 80 cm
Volume of container (V) =?
Volume = length × width × height
Volume = 76.2 × 80 × 60
Volume = 365760 cm³
Finally, we shall convert 365760 cm³ to litre (L). This can be obtained as follow:
1000 cm³ = 1 L
Therefore,
365760 cm³ = 365760 cm³ × 1 L/ 1000 cm³
365760 cm³ = 365.76 L
Therefore, the volume of the container is 365.76 L
Since the volume of the container (i.e 365.76 L) is bigger than the volume of the solution (i.e 170 L), therefore, the solution will fit into the container.

Which is the best way to determine if an object is made of pure silver?
O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.
Answer:
The correct option is;
Determine the density of the object and compare the known density of pure Silver
Explanation:
The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)
The density is then fond by dividing the weighed mass by the volume the object displaces when immersed
Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.

A brief explanation to this question: "Why are neon signs/fireworks different colors? Please help me. Do not look up internet
Answer:
when lit, the atoms of different chemical compounds inside the firework absorb energy, when the electrons fall back to lower energy levels, they give off colored light. Depending upon the chemical used, different colors are produced. neon lights or signs are glass tubes filled with neon gas. When the light is plugged in, the electrical energy causes the electrons of neon to jump to higher energy levels, when they go to lower levels, colored light is given off. The neat thing is that the neon never gets used up. The only thing that gets used up is the electricity. The electrons don't get destroyed and can be used over and over again jumping levels. Neon glows with an orange light, but you know that neon signs can be lots of different colors. The variations come when different gases other than neon are used such as argon, or krypton or when the tube is painted so that with the light produced it produces a certain color.
Explanation:
After being excited by high levels of electrical energy (as in neon signs) or heat energy, various elements and molecules will emit their own specific colors of light.
What are basis behind fireworks?Metals burn in a variety of colors. When a copper compound is lit, for example, the flame is blue-green.
Calcium burns red, while potassium burns purple. Metals are combined to produce various colors in fireworks.
The appearance of each firework is determined by the type of stars it contains, as well as the size and quantity of these pellets.
Some stars contain metal salts, which produce brilliant colors, while others contain a variety of chemical compounds that produce dazzling light effects such as strobing, sparkling, and others.
Various elements and molecules will emit their own specific colors of light after being excited by high levels of electrical energy (as in neon signs) or heat energy (as in the fireworks).
Thus, the neon signs or fireworks provide different colors.

How much heat is required to melt 42.0 grams of water at 0*C?
Hurry...
Answer:
Heat required to melt 42 g if ice is 13,860 J
Explanation:
The amount of heat required to melt grams of water at 0°C is given as follows;
The mass of the ice (water), m = 42 g
The latent heat of fusion of ice Δ[tex]H_f[/tex]= 330 J/g
Therefore, heat required to melt 42 grams is given as follows;
Heat required to melt ice = Mass of the ice, m × The specific latent heat of fusion of the ice, Δ[tex]H_f[/tex]
Heat required to melt 42 g if ice = m × Δ[tex]H_f[/tex] = 42 g × 330 J/g = 13,860 J
Heat required to melt 42 g if ice = 13,860 J.
